Gene Details:

• MSU gene ID: LOC_Os01g15900
• RAPdb gene ID: Os01g0264000
• Gene Symbol: RDD1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In addition, RDD1-AS plants were smaller and flowered later than WT or RDD1-S plants; decreases in grain length, width and 1000-grain weight were also recorded.
• This study demonstrates that RDD1 is a circadian clock and phy-regulated gene, which is associated with grain size in rice.
• Circadian clock- and phytochrome-regulated Dof-like gene, RDD1, is associated with grain size in rice.
• We report here on the characterization of a putative Dof transcription factor gene in rice (Oryza sativa)–rice Dof daily fluctuations 1 (RDD1).
• Moreover, the overexpression of RDD1 increased nitrogen responsiveness and grain productivity.
• Our results suggest that RDD1 can contribute to the increased grain productivity of rice via inducing the efficient uptake and accumulation of various nutrient ions.
• MicroRNA-targeted transcription factor gene RDD1 promotes nutrient ion uptake and accumulation in rice.
• Here, we show that the transcription factor encoding gene RDD1 plays a role in improving the uptake and accumulation of various nutrient ions in rice.
• In-frame editing of transcription factor gene RDD1 to suppress miR166 recognition influences nutrient uptake, photosynthesis, and grain quality in rice.
• The transcription factor-encoding gene RDD1 increases the uptake of nutrient ions, photosynthetic activity under ambient and high CO(2) conditions, and grain productivity, and microRNA166 (miR166) regulates its transcript levels.
• These results suggest that the in-frame mutagenesis of RDD1 to suppress miR166-RDD1 transcript pairing contributes to the improved grain appearance of rice.
